Musical-instruction device



Nov. 11, 1930. H. HOLZMAN MUSICAL INSTRUCTION DEVICE Filed June 21, 1928INVENTOR AT RNEY Patented Nov. 11, 1930 UlTED STATES PATENT VQFFIQEELMUSICAL-INSTRUCTION DEVICE Application filed June 21,

10 keyboard of the piano or the fingerboard of any other instrument.

The invention comprises two connected pointers which are separated bythe space of an octave on an illustration of a clef and its 15 legerlines so that when one pointer is used in the clef the other pointerindicates the corresponding note in the neXt octave.

In this way one pointer is moved along the clef and the other pointertravels along the 20 leger lines so that the note indicated by the legerpointer can be named by reference to the pointer on the clef.

In reading the treble clef the leger pointer would be above the clefpointer and reading 5 the bass clef the pointer would be below the clefpointer. The device can be combined however, for the two clefs and theleger pointers are above and below the central pointer so that thedevice can be used in both clefs.

The device is usually provided in the form of a card or tablet on whichthe clefs and the leger lines thereof are printed and the pointers arearrangedin a slideway and have a fingerpiece by which they can be movedin unison and for convenience the keyboard or other note selecting meansof an instrument can be printed alongside of the clefs to permit easyidentification of the note on 0 the chart.

The invention is illustrated in the accompanying drawing in which thefigure is a face view of a device embodying my improved musicinstruction chart with the device shown as being used for identifying anote in the treble clef and above the treble clef in full lines and asused in the bass clef in dotted lines.

The drawing illustrates a suitable support, usually a plain flat tabletor board having 1928. Serial No. 287,186.

the representation of the treble clef as at 11 and of the bass clef asat 12. The c'lefs are made up of the usual stalls and 1 usuallyillustrate both stafis on the chart and connect them by the brace. Theleger lines are also properly placed as at 1 above the treble staff andat 15 below the bass stafi.

lVith the chart I use connected pointers which are separated by adistance equal to the space of an octave on the chart and the pointersare therefore used by placing one pointer at a note on the stafl and theother pointer will therefor indicate the line or space the leger area ofthe corresponding note in the next octave.

For convenience these pointers are preferably placed on the chart itselfand mounted so as to slide therein.

1 illustrate a guide 16 in which the pointers are mounted, the pointersbeing usually struck up from a sheet of metal which shoes in the space17 the guide. The metal piece therefore forms a slide with the pointer18 to indicate ti e notes in the stall and the pointer 19 above it toindicate the same leger note. The staff notes are generally provided.with a. letter to assist in identi n To indicate the bass notes in theleger lines 1 provide the pointer 20 below the pointer 18. A suitablehandle 21 can be placed on the slide to make it easy to move thepointers.

In the illustration the pointer 18 points to the note C in the treblestall and the pointer 19 points to the leger position of he C in thenext higher octave.

ln dotted lines I the C in the bass eta position of the low I usuallyplace t show the pointer 18 at .d the pointer 20 at the in the legerarea.

e n te space of the instrument to the right of the chartas I show a.piano key-board as an illustration. key-board IQPIsSGlltiltlOIl is shownat 22 and the notes can be identified on the key-board as well as on therespective stafis and leger areas by this device.

Various modifications can be made in the device without departin fromthe scope of the invention.

I claim:

1. A musical instruction chart comprising illlS a representation of astaii and its leger lines, and connected pointer spaced apart thedistance of an octave on the chart whereby a leger'note can beidentified by one pointer 'when the other pointer is placed on thecorresponding note within the staff. I

2. A musical instruction chart'comprislng a representation of a.stafiand its leger lines,

a pair of pointers slid'ab-le alongside..tllecsiafi and separated by thespace of an 'octave on the chart whereby when one pointer indicates anote in the starlii' the other pointer lILCllCiLtQS the same note withinthe leger area and means on the chart for supporting the-pointers;

3. A musical instruction chart comprising a representation ofthe' treblestaff and the bass staff and their respective leger lines, and connectedpointers slidably arranged on the chart the centre pointer to indicatethe staff notes and the outside pointers to indicate corresponding notesin the leger areas and means for supporting the pointers on the chart.

4. A music instruction chart comprising a representation of the treblestafl and the bass sta'fi and their respective leger lines and a set ofthree equi-distant pointers separated by a space between pointers equalto an octave on the chart. 7

In testimony whereof I afiix my signature.

HERMAN HOLZMAN.
